Axillary surgical specimens showed perinodal fibrosis in 9\/48 (18.7%) patients. Interference with SLN dissection was reported in 4\/48 (8.3%) patients (two hematomas, three abnormal palpation findings, and four difficult dissections). The overall surgical detection rate of SLN was 43\/48 (89.6%). In the majority of cases, perinodal fibrosis was described as moderate (4\/9 [44.4%]) or severe (4\/9 [44.4%]). The mean time elapsed between CEUS\u2009+\u2009CNB and axillary dissection was shorter in patients with perinodal fibrosis (<jats:italic>P<\/jats:italic> =\u2009.04).
